Abstract

The present invention discloses a vehicle inspection system, comprising: an inspection passage; a vehicle dragging system arranged in the inspection passage, wherein the vehicle dragging system comprises a first dragging means and a second dragging means, which are sequentially arranged along a vehicle dragging direction, and in the vehicle dragging direction, the first dragging means is arranged at the upstream of the second dragging means, and a separating section is arranged between the first dragging means and the second dragging means, so that the first dragging means and the second dragging means are separated by a preset distance in the vehicle dragging direction; and a radiographic inspection system, wherein at least a part of paths of the beams of the radiographic inspection system passes through the separating section between the first dragging means and the second dragging means.

First claim

The invention claimed is:

1. A vehicle inspection system, comprising:
an inspection passage;
a vehicle dragging system arranged in the inspection passage, wherein the vehicle dragging system comprises a first dragging means and a second dragging means, which are sequentially arranged along a vehicle dragging direction, and in the vehicle dragging direction, the first dragging means is arranged at the upstream of the second dragging means, and a separating section is arranged between the first dragging means and the second dragging means, so that the first dragging means and the second dragging means are separated by a preset distance in the vehicle dragging direction;
a radiographic inspection system, wherein at least a part of paths of the beams of the radiographic inspection system passes through the separating section between the first dragging means and the second dragging means;
a gap is formed in the separating section, in order to let the beams pass the separating section without being obscured;
the vehicle inspection system has a first mode, a second mode and a third mode:
under the first mode, the vehicle voluntarily passes the inspection passage, and the radiographic inspection system inspects the vehicle by adopting a dosage lower than a first preset value, and
under the second mode, the dragging system drags the vehicle to pass the inspection passage, and the radiographic inspection system inspects the vehicle by adopting a dosage larger than or equal to a second preset value, wherein the radiographic inspection in the firs or second mode gathers data about the vehicle; and
a vehicle identification system for identifying a type of the vehicle, the vehicle identification system comprising a chassis camera system and in communication with the radiographic inspection system, wherein the vehicle identification system is configured to:
scan, by the chassis camera system, the chassis of the vehicle;
based on the scanning of the chassis of the vehicle, identify the type of the vehicle;
identify a license plate number of the vehicle; and
adopt a corresponding scanning inspection strategy according to the type of the vehicle, the license plate number of the vehicle, and the data gathered by the radiographic inspection system.

2. The vehicle inspection system of claim 1 , wherein the radiographic inspection system comprises:
a first radiation source arranged at one of the upper side and the lower side of the separating section between the first dragging means and the second dragging means,
a first detector at least partially arranged at the other one of the upper side and the lower side of the separating section between the first dragging means and the second dragging means and used for receiving beams emitted by the first radiation source and penetrating through the inspected vehicle, and
wherein the first radiation source is an X-ray beams accelerator or an X-ray beams machine.

3. The vehicle inspection system of claim 2 , further comprising:
a linear cantilever crane structure arranged near the ground of the inspection passage, wherein the first detector is arranged on the linear cantilever crane structure, and
at least a part of the linear cantilever crane structure is arranged near the ground of the separating section between the first dragging means and the second dragging means.

4. The vehicle inspection system of claim 3 , further comprising:
a transition means arranged on the separating section between the first dragging means and the second dragging means, and the transition means is used for supporting the vehicle when the vehicle moves from the first dragging means to the second dragging means, and
wherein the linear cantilever crane structure is arranged below the transition means.

5. The vehicle inspection system of claim 2 , further comprising:
a U-shaped cantilever crane structure, wherein the U-shaped cantilever crane structure comprises a substantially horizontal cantilever crane structure and two substantially vertical cantilever crane structures extending upwards from the two ends of the substantially horizontal cantilever crane structure, the substantially horizontal cantilever crane structure is arranged near the ground of the inspection passage, and the first detector is arranged on the substantially horizontal cantilever crane structure and the substantially vertical cantilever crane structures,
wherein at least a part of the substantially horizontal cantilever crane structure is arranged near the ground of the separating section between the first dragging means and the second dragging means, and
wherein the first radiation source is arranged above the separating section between the first dragging means and the second dragging means.

6. The vehicle inspection system of claim 5 , further comprising:
a transition means arranged on the separating section between the first dragging means and the second dragging means, and the transition means is used for supporting the vehicle when the vehicle moves from the first dragging means to the second dragging means;
wherein the substantially horizontal cantilever crane structure is arranged below the transition means.

7. The vehicle inspection system of claim 1 , wherein the radiographic inspection system comprises:
a second radiation source arranged at one side, in a transverse direction substantially perpendicular to an up and down direction and the vehicle dragging direction, of the separating section between the first dragging means and the second dragging means,
a second detector at least partially arranged at the other side in the transverse direction of the separating section between the first dragging means and the second dragging means and used for receiving beams emitted by the second radiation source and penetrating through the inspected vehicle, and
wherein the second radiation source is an X-ray beams accelerator or an X-ray beams machine.

8. The vehicle inspection system of claim 7 , further comprising:
an L-shaped cantilever crane structure, wherein the L-shaped cantilever crane structure comprises a substantially horizontal cantilever crane structure and a substantially vertical cantilever crane structure extending upwards from the end of the substantially horizontal cantilever crane structure, the substantially horizontal cantilever crane structure is arranged near the ground of the inspection passage, and the second detector is arranged on the substantially horizontal cantilever crane structure and the substantially vertical cantilever crane structure, and
wherein at least a part of the substantially horizontal cantilever crane structure is arranged near the ground of the separating section between the first dragging means and the second dragging means.

9. The vehicle inspection system of claim 7 , further comprising:
an inverted L-shaped cantilever crane structure, wherein the inverted L-shaped cantilever crane structure comprises a substantially horizontal cantilever crane structure and a substantially vertical cantilever crane structure extending downwards from the end of the substantially horizontal cantilever crane structure, the substantially horizontal cantilever crane structure is arranged above the inspection passage, and the second detector is arranged on the substantially horizontal cantilever crane structure and the substantially vertical cantilever crane structure.

10. The vehicle inspection system of claim 1 , further comprising
a transition means arranged on the separating section between the first dragging means and the second dragging means, wherein the transition means is used for supporting the vehicle when the vehicle moves from the first dragging means to the second dragging mea
